Abstract

The invention discloses a carbon potential operator which comprises a main controller and a mode setting unit. A programmable logic controller serves as the main controller. The main controller comprises a first carbon potential operation unit and a second carbon potential operation unit. The first carbon potential operation unit comprises a first temperature signal input interface, a first carbon potential signal input interface, a first carbonic oxide signal input interface and a first carbon potential output interface. The second carbon potential operation unit comprises a second temperature signal input interface, a second carbon potential signal input interface, a second carbonic oxide signal input interface and a second carbon potential output interface. The mode setting unit is connected with the first carbon potential signal input interface, the first carbonic oxide signal input interface, the second carbon potential signal input interface and the second carbonic oxide signal input interface. By means of the carbon potential operator, the using convenience and calculation accuracy of the carbon potential operator are greatly improved.

Description

technical field [0001] The invention relates to the field of heat treatment equipment manufacturing, in particular to a carbon potential calculator. Background technique [0002] In the carburizing equipment for heat treatment, it is necessary to measure and manage the parameters of the carburizing ability in the furnace (referred to as "carbon potential"), the carbon potential and the temperature of the atmosphere in the furnace, the content of carbon potential gas (carbon dioxide or oxygen) and carbon monoxide content is closely related. According to the type of carbon potential gas selected, the characterization methods of carbon potential include oxygen potential method and carbon dioxide potential method. The oxygen potential method can be expressed by the expression Cp=f(T, O2, CO), while the carbon dioxide formula can be expressed by The formula Cp=f(T, CO2, CO) represents, where: Cp represents the carbon potential in the furnace atmosphere, T represents the temperat...
